摘要： An electronic circuit comprises a delay circuit that with a chain of saw tooth delay stages (10a-d), coupled in a loop to form an oscillator for example. Each stage comprises an integrating circuit (104) and a current modulator (106) coupled to the integrating circuit (104). Each stage triggers a transition in the next stage when the integration result reaches a level defined by a reference voltage. Correlating circuitry (102, 30, 32, 34) is provided with current outputs to generate currents to the current modulators (106) and reference voltages for the saw tooth delay stages (10a-d). The reference voltages are generated at least partly from a common reference (102c), so that noise in the currents from the current modulators (106) and reference voltages is correlated in a way that at least partly cancels the effect of the noise on the delay time.

摘要： Circuitry that provides alternating current to a load from a unipolar power supply. A current source in the circuitry controls current applied to the load. A first switch and a second switch are connected between the load and the current source and allow current to flow from the current source to the load in a first direction responsive to the first switch and the second switch being closed. A third switch and a fourth switch connected between the load and the current source allow current to flow from the current source to the load in a second direction responsive to the third switch and the fourth switch being closed.

摘要： An impedance-steerable circuit (40) for an industrial phase controller (200) inserts precise steerable trigger pulses (32) in the sine and cosine excursions of a sine wave of high-energy capacitive and related discharge systems. Multiple pulses and Barkhausen effects are eliminated. The controller (200) can lock capacitive discharge systems (100) into precise phase or, in extended embodiments, serve as a power controller for radar systems, laser systems, and beam weapons. Thyristors (242) and thyratrons provide steered elements (pulses) activated in a pulse-feedback mode.

摘要： In a digital input/analog drive positioning system, in order to simplify the circuitry of the absolute difference generator used to calculate the magnitude and sign of the difference between the digital target input and the digital current position value, the pre-adder (31) magnitude comparator is omitted. One input (36) to the adder contains complementing circuitry (34) as does the output from the adder. The carry-out (38) from the adder (31) is latched and used to select connection by complementing or carry handling in response to application of a carry-in signal as well as to determine the sign of the difference (line 43) if both input and value are positive, additional circuitry being required else.
